Abstract
An activated magnetite catalyst is formed of activated iron oxide or iron particles with solid crystal lattice, from which oxygen is partly removed. When the activated mgnetite catalyst is prepared, oxygen is partly removed from solid crystal lattice of particles of Fe.sub.3 O.sub.4, Fe.sub.3 O.sub.4+x obtained by partly or entirely oxidizing Fe.sub.3 O.sub.4 or gamma-Fe.sub.2 O.sub.3. The catalyst is useful to decompose gaseous oxides.
